Sebastian Bax-)2 Patented Mar. 2, 1948 UNITED STAT ES PATENT OFFICE 2,437,019 streetcar manners Sebastian Eich, outage, Application December 26, 1946, Serial No. 718,361 2 claims. (01. 128 -1283) -1 My invention relate generally to surgical applianceaand more particularlyto an improved cold qi e 4 Considerable discomfortinconvenience is xr i shs i i i i 'b' e e'h h Q i9 m erforr'nd upon them, in a re anddi'sposing of heeiscparge from til in'ci sio Thed essings and p 5.11? tftfi sjli no f' lu t 'v shift from position over the incision and permit soiling. of the clothing by the discharge. This is most likelyto occur during jsl'e'em due w m n scious bodily movements, but also occurs accidentally at other times, especially in the course of physical work and exercise.

It is therefore the object of my invention to provide an improved simple and sanitary means for collecting and disposing of the discharge from a colostomy or similar incision.

A further object is to provide a receptacle, for the above mentioned purposes, which has means for frictionally holding it in position over the incision, which is provided with means to prevent escape of fluids therefrom, which is easily applied and removed, which is comfortable to the user, which is light in weight, and which may be economically manufactured.

Other objects will appear from the following description, reference being had to the accompanying drawings, in which:

Fig. l is a vertical diametrical sectional view of the receptacle, showing it applied to cover a colostomy or similar incision from which drainage or discharge may take place;

Fig. 2 is a side elevational view of the receptacle;

Fig. 3 is an elevation, taken in the direction of the arrows 33 of Fig. 2;

Fig. 4 is an enlarged fragmentary sectional view, taken on the line 44 of Fig. 3; and

Figs. 5 and 6 are diametrlcal sectional views of modified forms of the invention.

Referring to Figs. 1 to 4, the receptacle is illustrated as comprising a shallow circular cup Ill, preferably a die casting of an aluminum, magnesium, or similar light alloy, having an annular groove I2 of substantiallyrectangular cross section in the face of its rim. An annular friction ring and seal M has a portion 16 thereof of rectangular cross section expanded in the groove l2 so as to be frictionally held therein. The ring it is preferably made of soft rubber or synthetic rubber substitute, sufficiently soft to conform readily to irregularities in the contour of the body surrounding the incision, and to yield slightly with bodily movement.

To render the ring more easily deformable forthe above mentioned purposes, it may be in the tact With form of a thick-walled. tube having a central an nular air space [8. The :portion 20 of the ring l6 preferably has a. rounded surface for contact with theskin, of the user, this surface bein smooth and soft so, as to minimize the possibility of irritation by chafing; -1

The wall of the cup in is preferably as'thin as is compatible with its necessary strength and rigidity, and itsqexterna-l surface. is that of a small segment, of .a sphere; so that its protuberance isnot noticeabie whenzinuse'. v p A filler padj22; preferably a laminated disc, comprising a thick central layer 24 of absorbent cotton and outer layers 25 and 26 of cotton gauze, fits in the cup l0, being of sufiicient size to cover completely the inner surface of the cup, and preferably having its edge projecting a short distance from the rim of the cup so that it will contact the body of the wearer as shown in Fig. 1.

In use, the receptacle with its filler pad, is placed over the incision as shown in Fig. l, and is held in place by an elastic web health belt 30. This belt presses the receptacle against the skin, with the surface 20 of the soft rubber ring in conthe skin and frictionally gripping it. This ring also forms a seal to prevent leakage of the discharge from the receptacle.

If desired, the body of the receptacle may be molded of a suitable lightweight synthetic plastic. For the sake of durability, and to obtain the desired softness and elasticity, the ring l6 may, if desired, be made of a suitable synthetic rubber substitute, which is resistant to the discharge, and will not deteriorate materially in use.

It will be noted that the sealing ring l6 may be removed from the groove l2 by pulling it therefrom, and readily replaced when it is desired to wash the receptacle.

If desired, the receptacle may be made of sheet metal in the manner shown in Figs. 5 and 6.

In Fig. 5, there are two sheets 34 and 36 which are generally of the shape of a small segment of a sphere, the rims of these formed sheets being oppositely flanged to provide an annular groove '38 for the reception of part of the sealing ring 4!! which is made of soft metal or synthetic rubber. An absorbent pad similar to the pad 22, may readily be inserted in the receptacle formed by the two sheets 34 and 36. It will be noted that the sealing surface 42 of the ring 40 has a relatively large radius of curvature, so as to provide a substantial area of contact with the body and thereby effeet a better seal and frictional grip. The sheets 34 and 35 may be secured together by any suitable soldering or welding or brazing method, or may be so conformed that they wili adhere to one another due to a press fit.

The modification shown in Fig. 6 includes but a single cupped disc 46, the major portion of which is of generally spherical contour, and the rim of which is formed with a hollow opening bead 48 for the reception of the holding portion 50 of a sealing member 52. As in the construction of Fig. 5, the sealing member is provided with a body contact surface 58 of a large radius of curvature, thereby having the aforesaid advantages of providing a better seal, assuring a tight frictional grip, and distributing the pressure applied by the elastic belt over a greater area of the body so as to render the wearing of it more comfortable. The receptacle of Fig. 6 is likewise used with a suitable absorbent pad.

While I have shown and described preferred embodiments of my invention, it will be apparent that numerous variations and modifications thereof may be made without departing from the underlying principles of the invention. I therefore desire, by the following claims, to include within the scope of the invention all such variations and modifications-by which substantially the results of my invention may be obtained through the use of substantially the same or equivalent means.

I claim:

1. A receptacle for the collection of the discharge draining from a bodily incision and which i is adapted to be held over the incision by an elastic belt without causing an appreciable protuberance,

which comprises a shallow cup-like member having an annular groove in its edge. and a removable annular soft rubber-like tubular sealing member having a portion fitting snugly in said groove and retained therein solely by the friction and elasticity Of the sealing member, said sealing member having a rounded surface for contact with the body.

2. The combination set forth in claim 1, in which the receptacle isrmade of two generally similarly formed concave sheet metal discs, with the edges of the discs flanged to provide the annular groove for the reception of the holding portion of the sealing member.
